“The ring is rose-cut diamonds set in rose gold,” a friend told OK! “It’s a very feminine piece of jewelry and very old.”

So, did anyone see him buy it? No, it was bought through a friend who specializes in estate sales, according to OK!

“The diamonds aren’t huge, and it doesn’t look like an engagement ring,” the friend said. “Rob is more mature than Kristen and he’s ready to settle down.”

Hmmm…we’re not buying it. OK! magazine isn’t exactly known for its journalistic integrity.

One thing we do know: RPatz isn’t exactly the picture of sexy in the bedroom, according to his Water for Elephants co-star, Reese Witherspoon.

“Rob possibly had the most hideous, horrible cold of any co-star I’ve ever had to do a love scene with ever in my entire life,” Witherspoon revealed recently. “He was literally snorting and snotting through every second of it — and it was not appealing. I’m talking green, infectious, disgusting — I’m not kidding!”

Ewwww. We can’t blame the guy though — everyone gets sick! She also said the British hottie was a dirty, dirty boy.

“Well, it’s a boy thing, right? To have dirty fingernails and dirty hair, and his clothes were dirty all the time,” Witherspoon said when asked about Pattinson’s personal hygiene.

No love lost, though — Pattinson said that his favorite co-star during filming was the elephant.

“I think I had a relationship with the elephant, [but] it was kind of based purely on candy,” he said last month at WonderCon. “I strategically placed mints, like, [I] suck[ed] on a peppermint for a bit and then stick it onto [my] body, like into my armpits…and [I didn’t] tell anyone. So every single time the elephant would be constantly sniffing me, and I’d be like, ‘I don’t know, she just really likes me, it’s crazy!’ But yeah, I think she was just sniffing around for a treat.”

Um…okay. Here’s hoping he took out the peppermint before the love scenes.
